However, in the past, the mounting frames for the directly mounted work machine and the three-point link machine for the front mounted machine were independent, which resulted in a very complex structure and complicated handling during attachment and detachment. In addition, directly mounted work machines such as front loaders have a pair of left and right booms that are located on both sides of the vehicle body and project forward, so when using Naobishi work machines, they may interfere with the front bag three-point link mechanism. There was some manipulation. The present invention solves the problem of such a substructure, and its special feature is that mounting frames are provided on both sides of the vehicle body, and each mounting frame is provided with left and right mounting frames located on both sides of the vehicle body. In a wheel to which a working machine is attached, which is equipped with a pair of booms that can be raised and lowered, a connecting frame is provided that connects the front ends of each mounting frame, and an upright frame that stands upward in front of the vehicle body is attached to this connecting frame. A top link mounting base for the front three-point link mechanism and an IJ foot arm for raising and lowering the front three-point link mechanism are located between the two mounting frames on the upper side of the upright frame. It is at the point set in .

Reference numeral 42 denotes a front-mounted working machine such as a grass cutter, which is detachably attached to the front of the truck body 1 via a front three-point linkage mechanism 43. The front three-point link mechanism 43 includes one top link 44 and a pair of left and right lower links 45, and the top link 44 is attached to a top link mounting base 46 fixed to the center of the connecting cylinder 35. It is removably attached to by a mounting pin 47. Each lower link 45 is inserted between the side plate 11 and the upright frame 34 below the lift cylinder 40 and is supported by a mounting pin 48, and is lifted from the mounting pin 50' via a lift rod 49 at the intermediate portion. It is connected to an arm 39. Mounting pin 41
, 48 are inserted into the insertion/removal position across pin holes formed in the side plate 11 and the upright frame 34, respectively, and the mounting pins 5 and 48 are inserted into the insertion/removal position at the front end of the lift arm 39.
Therefore, the front three-point linkage mechanism 43 can be attached to and detached from the mounting frame 10' of the tractor body 1. Note that a notch 51 is formed at the upper end of the upright frame 34. In the above configuration, when the front loader 20 is mounted on the truck body 1, the fixed frame 25 is first separated from the support 24, and the mounting plate 26 of the fixed frame 25 is mounted on the mounting plate 14 of the mounting arm 12. At the same time, fix the front end of the reinforcing frame 28 with the bracket 3 and the bolt 27.
Fix it by. After attaching the fixing frame 25 to each attachment frame 10 of the truck body 1 in this way, the boom 21 is supported with the bucket 23 grounded and the support body 24 at an appropriate height. The support body 24 may be iron-coupled with the mating portion of the fixed frame 25 by moving the vehicle body 1, and the support body 24 may be fixed to the fixed frame 25 with a mounting pin or the like. At this time, the top link 4 constituting the front three-point link mechanism 43
4. The lower link 45, lift rod 49, etc. are installed, and the upright frame 34, lift arm 39, top link mounting base 46, etc. are located between the left and right pair of side plates 11, and within the width of the bonnet 8. Since these booms 21 are provided, there is no problem when raising and lowering the boom 21, and therefore there is no need to increase the distance between the booms 21, and the work is easy.

That is, while connecting the top link 44, the side plate 11
Insert the rear end of the lower link 45 between the and the upright frame 34,
They are connected by a mounting pin 48. Further, each lower link 45 is connected to the lift arm 39 via a lift rod 49. Once the installation of the front bag three-point link mechanism 43 is completed in this way, it is only necessary to connect the front load working machine 42 to the front end of each link of the front bag three-point link mechanism 43. Due to the expansion and contraction movement of the cylinder 49, the lift arm 39
It is possible to raise and lower the muzzle-mounted working machine 42 via the front bag three-point link mechanism 43, and it is also possible to move the muzzle-loading working machine 42 up and down by a tractor via the front bag three-point link mechanism 43. The mounting bracket 30 is shown in FIGS. 7 and 8.
As shown in the figure, the front end of each side plate 11 may be bent slightly outward and formed integrally.

Further, as shown by the imaginary line in FIG. 8, if a pin portion 52 for connecting the reinforcing frame 28 is integrally formed with the outer end of the mounting pin 48 for the lower link 45, the mounting bracket 30 can be omitted. . In the present invention, since the front ends of the support frames for working machines attached to both sides of the vehicle body are connected by the connecting frame, the reinforcing effect of the attachment frame on the vehicle body is significantly improved.

In addition, this mounting frame is equipped with a top link mounting base for the front three-point link mechanism and an upright frame that supports the lift arm, so the mounting frame can be used as part of the front three-point link mechanism. It is possible to reduce the amount of materials used. Moreover, the top link mounting base and lift arm are installed on the upright frame so that they are located inward from the left and right mounting frames, so when using the work equipment, they do not interfere with the boom and work can be done quickly. is possible.
